I first thought about before purchasing this product. I already had good memories for burn DVD manufactured by Verbatim purchased in smaller quantities. 2, 3 first engravings were neat, but not the following. Indeed only a fifth of dvds appear to be in perfect condition. My prints always fail. Of course I compared the storage capacity of DVDs compared to my files. I never had such problems before. The product is, however, arrived in excellent condition. I found a good price but now I regret this purchase value for money is not there.
